[Qemu-devel] [PULL 17/57] tests/qgraph: ppc64/pseries machine node

[Paolo Bonzini <pbonzini@redhat.com>]

From: Emanuele Giuseppe Esposito <e.emanuelegiuseppe@gmail.com>

Add pseries  machine for the ppc64 QEMU binary. This machine contains a
spapr-pci-host-bridge driver, that contains itself a pci-bus-spapr
that produces the pci-bus interface.
